MANTLE AND MANTLE-SUPPOBTIOR INCANDESCENT: GAS-LlGHTS.

SPECIFICATION forming part of I etters Patent No. 662,381, dated November 20, 1900. Application filed lliarch 1, 1900. Serial No. 6,974- No model'tl To allwhom it .mcty concern.-

Be it known that we, MAX HERSKOVITZ and ABRAHAM I. HERSKOVITZ, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Mantles and llIantle-Suppo'rts for Incandescent Gas-Lights and we do hereby declare to make and use the same.

This invention has relation to mantles and.

fmantle-snpporters for incandescent gaslights, and has for its object the provisionot' a novel means for supporting the mantle abovethe gas-flame.

The invention consists, first, in-providing the mantle with a wire or metal loop which is attached to the upper end of the mantle by means of an asbestos cord or filament and constitutes a means for the suspension of the mantle from the adjustable supporting-rod, and, second, in constructing the mantle supporting and suspendingrod with double suspension-hooks adapted to engage with opposite sides of the mantle-loop and support the mantle firmlyon the center of the burner.

In the accompanying drawings, Figure 1 is a side elevation of a burner for incandescent gas-lights with our invention applied thereto. Fig. 2 is a side view of our improved mantle. Fig. 3 is a side view of our improved double mantle'suspension rod.

The mantle A is of the usual or any suitable character; but instead of being provided with the usual suspension-loop made of asbestos cord it is provided with a wire or metal loop 13, formed witlrrings or eyes a, a on opposite sides. This wire or loop is fastened by a thread or filament of asbestos b to the upper contracted and crimped end of the mantle, as shown.

Q represents the mantle-supporting rod, which, according to -ur invention, consists of a suitable length of wire bent over at its upper end as shown at.c,-.and formed at the end of c with a hookd. The vertical section of this Wire is formed with two eyes or rings 0 c, as by bending the wire around a man drel, and in these eyes or rings the stem d of a supplementary suspension-rod D or wire D is inserted and tightly held. The upper end of the wire D is bent at d and formed with a hook d similarly to that of the wire or rod 0. The two wires are spread apart at their upper ends and the eyes a, dot the 1 looped wire B hung thereon, as shown. The

mantle being thus supported or suspended from two opposite points can be more accurately adjusted centrally over the burner than where there is, as usual, but one point of suspension, as either wire can be adjusted relatively to the other and the mantle thereby fixed in the required position, and when in position is not liable to be thrown accidentally out of position. The supporting-hooks not being over the center of the flame are not liable to become overheated and destroyed. It desi red,the supporting-hooks may he closed together and the mantle supported by hanging the central bend f on the loop .1; upon the two hooks.

Having described our invention, we claim and desire to secure by Lettters Patent- '1. A mantle for incandescent lights, having a stiff suspension-wire attached to its upper end at two opposite points and formed with a loop at each end outside the pornts of attachment.

2. A supporting-rod for mantles consisting of two bent hook-ended wires, one having a straight shank and the other havinga shank with eyes embracing said straight shank, said Wires being relatively adjustable substantially as described.

3. A l mantle for incandescent gas-lights havinglat its. upper end a suspension-wire, looped Eat its ends, and bent between'the loops, do that it may be supported from the sides or center, substantially as described.

. L. The combination with a mantle having a double-looped suspension-wire atits upper.
